I have a signed etching that has a stamp of a crown with a "c" in the middle and also a stamped image of an academic in academic garb. The etching looks like it was done at the turn of the century. The scene is an academic building and seated on a bench is a scholar. Also walking down the walkway is a couple. Any idea of who did this etching, where it was done or when? It is signed in pencil but I can't make out the name. It looks like an L for the first name and possible O'M... for the last name?

What kind of etching is it? Type of metal, etc. Or, is it made of wood? How large is it?
